4.5. Topicality of information
Ensuring the topicality of information is the primary commodity that MediaWiki resources provide in comparison to classic publication schemes; they also represent a significant challenge to ensure the sustainability of the resource. If information is not regularly updated, the wiki environment ceases to work as it should and the content of the resource declines. This also applies to URL addresses which the resource cites and which are important for verifying the information. If these addresses are not regularly updated, many links become broken over time.
